Armstrong Whitworth
Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne, Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft. The company was founded by William Armstrong in 1847, becoming Armstrong Mitchell and then Armstrong Whitworth through mergers.

Biofouling
Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals where it is not wanted on surfaces such as ship and submarine hulls, devices such as water inlets, pipework, grates, ponds, and rivers that cause degradation to the primary purpose of that item. Such accumulation is referred to as '' epibiosis'' when the host surface is another organism and the relationship is not parasitic. Since biofouling can occur almost anywhere water is present, biofouling poses risks to a wide variety of objects such as boat hulls and equipment, medical devices and membranes, as well as to entire industries, such as paper manufacturing, food processing, underwater construction, and desalination plants. Anti-fouling is the ability of specifically designed materials (such as toxic biocide paints, or non-toxic paints) to remove or prevent biofouling. The buildup of biofouling on marine vessels poses a significant problem. In some instances, the hull struc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-boats
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Ostend Raid
The First Ostend Raid (part of Operation ZO) was the first of two attacks by the Royal Navy on the German-held port of Ostend during the late spring of 1918 during the First World War. Ostend was attacked in conjunction with the neighbouring harbour of Zeebrugge on 23 April in order to block the vital strategic port of Bruges, situated inland and ideally sited to conduct raiding operations on the British coastline and shipping lanes. Bruges and its satellite ports were a vital part of the German plans in their war on Allied commerce ('' Handelskrieg'') because Bruges was close to the troopship lanes across the English Channel and allowed much quicker access to the Western Approaches for the U-boat fleet than their bases in Germany. The plan of attack was for the British raiding force to sink two obsolete cruisers in the canal mouth at Ostend and three at Zeebrugge, thus preventing raiding ships leaving Bruges. The Ostend canal was the smaller and narrower of the two channels g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ostend
Ostend ( nl, Oostende, ; french: link=no, Ostende ; german: link=no, Ostende ; vls, Ostende) is a coastal city and municipality, located in the province of West Flanders in the Flemish Region of Belgium. It comprises the boroughs of Mariakerke, Raversijde, Stene and Zandvoorde, and the city of Ostend proper – the largest on the Belgian coast. History Origin to Middle Ages In the Early Middle Ages, Ostend was a small village built on the east-end () of an island (originally called Testerep) between the North Sea and a beach lake. Although small, the village rose to the status of "town" around 1265, when the inhabitants were allowed to hold a market and to build a market hall. The major source of income for the inhabitants was fishing. The North Sea coastline has always been rather unstable due to the power of the water. In 1395 the inhabitants decided to build a new Ostend behind large dikes and further away from the always-threatening sea. 15th to 18th century The s ...

Scuttling
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self destruct, self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a Channel (geography), channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a Cog (ship), cog preserved from the keel up to the decks in the silt was discovered alongside ...

Guard Ship
A guard ship is a warship assigned as a stationary guard in a port or harbour, as opposed to a coastal patrol boat, which serves its protective role at sea. Royal Navy In the Royal Navy of the eighteenth century, peacetime guard ships were usually third-rate or fourth-rate ships of the line. The larger ships in the fleet would be laid up "in ordinary" with skeleton crews, the spars, sails and rigging removed and the decks covered by canvas – the historic equivalent of a reserve fleet. By contrast the guard ships would carry sails and rigging aboard, be defouled below the waterline to increase their speed under sail, and be manned by at least one quarter of their normal crew. A port or major waterway may be assigned a single guardship which would also serve as the naval headquarters for the area. Multiple guardships were required at larger ports and Royal Dockyards, with the largest single vessel routinely serving as the Port Admiral's flagship. If war was declared, or an en ...

Battle Of The Yser
The Battle of the Yser (french: Bataille de l'Yser, nl, Slag om de IJzer) was a battle of the First World War that took place in October 1914 between the towns of Nieuwpoort and Diksmuide, along a stretch of the Yser River and the Yperlee Canal, in Belgium. The front line was held by a large Belgian force, which halted the German advance in a costly defensive battle. The victory at the Yser allowed Belgium to retain a small strip of territory, with Germany in control of 95 per cent of Belgian territory, which made King Albert a Belgian national hero, sustained national pride and provided a venue for commemorations of heroic sacrifice for the next hundred years. Background German invasion of Belgium On 2 August 1914, the Belgian government refused passage through Belgium to German troops and on the night of the Belgian General Staff ordered the Third Division to Liège to obstruct a German advance. The German army invaded Belgium on the morning of 4 August. Covered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
